B.COTTRELL & SONS COMPANY, OF WESTERLY, RHODE ISLAND, A CORPORATION OFDELAWARE ROTARY ram'rma ranss Application filed May 1 ,1928, Serial No.278,671.

The object of my invention. is to provide means whereby the formcylinder may be independently adjusted, both rotatively with respect toits driving means and in anend- Wise direction, especially while thepress is running, so that the form on the cylinder may be brought intolongitudinal and lateral register easily and quickly; thereby obviatingthe necessity of shifting the form on its cylinder, which latter must bedone while the .press is at rest and at a considerable loss of printingtime.

- A practical embodiment of my invention represented in the accompanyingdrawings, in which Fig. 1 represents a detail side view of the printingpress showing the two mechanisms for adjusting the form cylinder bothrotatively with respect to its driving means and in an endwise directionlaterally of the frame.

Fig. 2 represents a detail transverse vertical section taken in theplane of the line IIII of Fig. 1, looking in the direction of thearrows; 1

Fig. 3 represents a detail transverse horizontal section taken in theplane of the line III-III of Fig. 1, looking in the direction of thearrows.

Fig. 4 represents a detail longitudinal vertical section taken in theplane of the line IV- -IV of Fig. 2, looking in the direction of thearrows.

Fig. 5 represents a detail longitudinal vertical section taken in theplane of the line V-V of Fig. 2, looking in the direction of the arrows.

The form cylinder 1 of the printing press has the oppositely projectingends 2 and 30f its shaft rotatably mounted for endwise movement insuitable bearings 4: and 5 in the sides 6 and 7 respectively of theprinting press frame.

The spiral wide faced form cylinder gear 8 is slidably interlocked withthe end 3 of the form cylinder shaft, in the present instance by makingthe gear hollow and providing its bore 9 with longitudinal grooves 10for slidably receiving the feathers 11 secured on the enlarged portion12 of the shaft end 3 located within said gear.

The form cylinder driving means includes a geasr 13meshing with the formcylinder gear The mechanism for adjusting the form cylinder rotativelywith respect to its driving means while the press is running, is asfollows:

The outer end of the form cylinder gear 8 is provided with a plate 14havin a trunnion 15 on which is loosely mounte the hub 16 of a yokehaving four arms 17, 18 and 19, 20, a collar 21 fast on the trunnionserving to causethe form cylinder gear 8 to be moved across the face ofthe driving gear 13 by the movement of the yoke. Two operativelyconnected hand screw shafts 22, 23, are located on opposite sides of thegear 8, which shafts are rotatably mounted against endwise movement inthe side frame 7 and have screwthreaded engagements with the oppositearms 17, 18 of the gear moving yoke. A sprocket chain 24 passes aroundsprockets 25, 26 fast on the said hand screw shafts 22, 23 so that theseshafts may be moved in unison. These shafts may be provided with:pitable hand wheels 27 28 for manipulating iem.

The mechanism for adjusting the form cylinder in an endwise directionwhile the press is running without disturbing its rotative adjustment islocated on the same side of the frame as the mechanism for adjusting theform cylinder rotatively, and it is constructed and arranged as follows:

The hub 29 of a yoke having two arms 30, 31 is loosely mounted on theend 3 of the form cylinder shaft inside the side frame 7, between theformv cylinder and a collar 32 fast on the shaft so that the cylinderwill be moved endwise by the yoke. Two operatively connected hand screwshafts 33, 34 located on-opposite sides ,of the form cylinder gear 8 arerotatably mounted against endwise movement in the side frame 7 and havescrewthreaded engagements with the arms 30, 31 of the cylinder movingyoke. These hand screw shafts pass freely through the opposite arms 19,20 of the gear moving yoke for preventing it from turning as it is movedalong said shafts. A. sprocket chain 35 for passes around sprockets 36,37 fast on said shafts 33, 34 so that the shafts may be moved in unison.These shafts may be provided with suitable hand wheels 38, 39 formanipu- 5 lating them..

It will be seen from the above description that the form cylinder may beadjusted to bring its form into proper register even though the press berunning, the adjustments for the longitudinalposition and the lateralposition of the form being made independently and the means forcontrolling these adj ustments being located conveniently for theoperator. v

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdepartment from the spirit and scope of my invention; hence, I do notwish to be limited to theparticular embodiment herein shown anddescribed, but
